Abstract

We report a high-resolution x-ray diffraction study of the freezing transitions of krypton on graphite for coverages above one monolayer. For pressure $P > 430$ Torr there is a single continuous incommensurate-fluid-to-incommensurate-solid freezing transition. For $P < 430$ Torr the freezing at fixed pressure is doubly reentrant with the succession of phases fluid → commensurate solid → reentrant fluid → incommensurate solid. The first transition is of first order, whereas the other two are continuous within the experimental resolution.
